Why is the total cost of fuel when a driver averages 8 miles per gallon..The cost of fuel is .83 cents a gallon..The drivers dis
Allushta [10]

Answer:

The total cost of the petrol is 2.075 cents.

Step-by-step explanation:

The cost of per gallon petrol = 0.83

Drive per gallon = 8 miles

Here, total distance traveled = 20 miles.

So, the total petrol used for 20 miles = (20 / 8) gallons

= 2.5 gallons

Now, cost of petrol per gallon = 0.83 cents

So, total cost of petrol = 0.83 x 2.5  = 2.075 cents

Hence, the total cost of the petrol is 2.075 cents.

Answer:

$40 in interest and $240 in total

Please do it in substitution method. Thanks.​
alina1380 [7]

Answer:  No solution

<u>Step-by-step explanation:</u>

x - 3y = 2   →     x = 3y + 2

2x - 6y = 6

2(3y + 2) - 6y = 6        <em>substituted x with 3y+2</em>

6y + 4 - 6y = 6            <em>distributed 2 into 3y+2</em>

        4        = 6           <em>simplified (6y - 6y = 0)</em>

4 = 6 is a FALSE statement so there is NO SOLUTION
